Here are some images of the Canadair CL-215/415 to help those working
on the Heller kits to add more detail.

These walk-arounds are based on a selection of aircraft seen around local
airports in Edmonton, Alberta and Abbotsford, B.C. The Canadair CL-215 and
CL-415 are basically the same airframe, but the turbine powered version has the
added winglets and horizontal stabilizer fins which assist in directional
control due to the higher thrust and torque of the turbine engines.

To supplement these photos, one of the best detail references for the
Canadair CL-215 is Volume 14, #4 issue of IPMS Canada's "Random
Thoughts" magazine.
